What is a feature of an open head drum?

An open head drum is characterized by having a removable head that is secured with a separate ring, often referred to as a bow or closure ring. This design allows for easy access to the contents of the drum, making it suitable for applications where the material needs to be frequently added or removed. The removable head design is essential for operations involving bulk materials, as it facilitates more efficient loading and unloading.

In contrast, a fixed head drum cannot be opened and is typically used for storage or transportation of liquids or solids that do not require easy access, which is not a feature of an open head drum. The presence of a single opening on top would more accurately describe other forms of containment that either do not allow easy access or are not designed for repeated access, such as certain types of closed head drums. The removable head attached by a secure latch might suggest a different locking mechanism that does not typically define the standard design of an open head drum, which specifically utilizes a separate ring for closure.
